The Gravity Forms logo in the page header is dark with a transparent background. I know you lot are fond of Halloween and all, but you might prefer it to be a bit less ghostly for the rest of the year!
I dunno man, looks OK to me!
Seriously though, thanks for the feedback. I’ll see what we can do about that.
UPDATE: I disabled the ability to select that theme.
I’m taking that approach with plugin support tickets from now, thanks for the tip!
